I'm brainstorming things my fiancee and I can do this winter to help us stay in shape. We are usually much, much more active in the warm months because we love the outdoors (hiking, backpacking, running, biking, etc.) but I'm determined to keep up the activities this winter before our May wedding. Important points to consider include: 1) I hate (really, really hate) gyms. 2) We live in New England (long, cold, snowy winters). 3) My fiancee does not ski.
